1.set注入:通过setXxx()赋值
<bean id="student" class="org.lanqiao.entity.Student">
<property name="stuNo" value="2"></property>
<property name="stuName" value="ls"></property>
<property name="stuAge" value="24"></property>
</bean>
2.构造器注入:通过构造方法赋值
<bean id="student" class="org.lanqiao.entity.Student">
<constructor-arg value="24" type="int" index="1" name="StuAge"></constructor-arg>//如果 <constructor-arg>的顺序 与构造方法参数的顺序不一致,则需要通过type或者index或name指定。
<constructor-arg value="ls" type="String" index="0" name="StuName"></constructor-arg>
<constructor-arg value="2" type="int" index="1" name="StuNo"></constructor-arg>
</bean>
3.p命名空间注入
xmlns:p="http://www.springframework.org/schema/p"//引入p命名空间
<bean id="student" class="org.lanqiao.entity.Student" p:stuNo="2" p:stuName="zs" p:stuAge="22">
</bean>
//8+String:p:属性名="属性值"
//引用类型:p:属性名-ref="引用的id"
